Assuming that you're using the Hobbit client on the Linux box, you
can just configure the client to only go red if the actual memory
usage goes above a certain threshold. In your hobbit-clients.cfg,
you would have

HOST=linux.foo.com
    MEMPHYS 100 101
    MEMACT   80  95
    MEMSWAP  40  70

Then it will stay green as long as the "actual" memory usage is 
below 80%, go yellow when it's between 80-95%, and go red when
it is at 95% or higher.
